' WHEELED PLOW.

Specification of Letters Patent.

Patented Apr. 15, 1919'.

Original application filed December 17, 1915, Serial No. 67,338. Divided and this application led January To all 'whom it may concern Bc it known that I, HARRY S. DIoKINsoN, aI citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Wheeled Plows, of which the following is a specication, reference being had therein to the accompanying drawing, being a. division of original application filed December 17th, 1915, ser. No. 67,338.

This invention relates to disk plows and has reference more particularly to the means for mounting the disk bearing on the frame of the machine in order that the angle of the.

disk relative to the surface of the ground may be varied to meet the varying conditions encountered in practice with respect to the nature of the soil. j

In the use of disk plows it is desirable to change the angle of the disk relative to the surface of the ground, comparatively hard ground requiring that the disk extend at a greater angle or in a more horizontal position, than when the ground is of a softer nature.

My invention consists of an imgproved means for connecting the disk bearing support to the frame, whereby the bearing may be adjusted to vary the angle of the disk in a speedy, convenient and simple manner and without interfering with the rigid and rm support of the disk bearing.

In the accompanying drawings:

Figure l` is a top plan view of such portions of a disk plow as will be necessary to illustrate my invention.

Fig. 2 is a vertical transverse sectional elevation through the same on the line awa.

Fig. 3 is a perspective view of the details of the disk bearing support and associated parts separated from. each other.

Referring -to the drawings:

1 designates the member of the machine frame which supports the disk bearing, which frame member in the present instance is in the form of a horizontal frame bar provided on its outer furrow side with upper and lower supporting surfaces in the form of ribs 2.

3 designates the disk bearing in which the disk 3'1L is rotatably'mounted, which bearing is seated in a socket in the lower end of an upright bracket 4 provided in its inner face Serial No. 209,826.

with upper and lower horizontal parallel grooves 5. These grooves receive respectively the ribs 2 on the frame member, the bracket being firmly fastened to the frame member by means of horizontal bolts 6 passing through the bracket and frame member and serving to connect the two in firm and fixed relations.

7 designates an adjusting lever which is adapted to be inserted between either of the grooves and the corresponding rib so as to incline the bracket forwardly or rearwardly according to whether the liner is applied above or below the fastening bolts.

The liner is in the form of a strip or plate of concavo-convex form in cross section, containing in one side a groove 8 which embraces the rib 2 and at its opposite side entering t-he groove in the bracket member. Then the liner is seated as shown in Fig. 2 between the` lower rib on the fra-me bar and the lower groove in the bracket member, the lower end of the latter will be tipped or inclined outwardly and the disk will be sustained on a corresponding angle suitable for operating in hard soil. When, however, the liner is transferred to between the upper groove and rib, the bracket will be tipped rearwardly at its lower end from nearly the vertical to ladapt the disk to Operate in softer ground. An intermediate adjustment may be obtained by removinp the liner entirely and connecting the bracket to the bar with both ribs thereon engaging directly in the grooves in the bracket.

It will be seen, therefore, that this construction provides for the adjustment of the disk to three different positions and that when the bracket is tightened up by the fas. tening bolts, either with or without the liner, the parts will be firmly and securely held without liability of becoming displaced or working out of their adjusted position.

While in the accompanying description and foregoing drawings I have set forth my invention in the particular detailed form which I prefer to adopt it will be understood that these details may be variously changed and modified without. departing from the limits of my invention; and further it will be understood that the invention is not limited to any particular form or construction of the parts eXceptin so far as such limitad tions are specified in the claim.-

Having thus described my invention, what vI claiin is:

In a disk plow, the combination of a frame member having upper and lowerV horizontal supporting ribs7 an upright disk-supporting bracket having upper and lower grooves, said bracket being applied to the frame member with the ribs and grooves in registry with each other, a releasable fastening bolt extending through the bracket and frame member between the ribs and rooves and acting to clamp the supporting racket Vixedly to the frame member, and a removable elongated adjusting linerof concavoconvex form in cross section, said liner seated in one of the grooves in the supporting bracket and embracing the opposing rib on the frame member, and being disposed free of and beyond the fastening bolt and serving to maintain the bracket at a given inclination, said liner being adapted to be removed and seated in the other groove of the bracket without removing the fastening bolt, to maintain the bracket at a different inclination.

In testimony whereof, I have aXed my signature hereto.
